General Description:
The AK4183 is a 4-wire resistive touch screen controller that incorporates SAR type A/D converter. The AK4183 operates down to 2.5V supply voltage in order to connect a low voltage drive processor. The AK4183 can detect the pressed screen location by performing two A/D conversions. In addition to location, the AK4183 also measures touch pressure.
